From Hansard, thanks to someone whose finger is more on the pulse than mine....
Pete Wishart: To ask the Secretary of State for Defence pursuant to his answer of 15 March 2005, Official Report, column 189W, on Trident, if he will estimate the number of potential casualties which would arise from a malfunction of a Trident nuclear warhead at the base on the Clyde. [223301]
Mr. Hoon: It is highly unlikely that a malfunction of a nuclear warhead resulting in a nuclear explosion would occur at the Naval Base on the Clyde. There are no plans to make assessments of potential casualties.
As my learned friend added: "(I say, what was that noise?)"
